LAMP-BURNEBJ Specification of Letters I'atent.

TO CZZZLOhO m it may concern: t v

Be it known that I, VIRGILwH. MILLs,-a

citizen of the United States, residing at Hubbard, in the county of Hilland State of Texas, have invented certain new and useful Improvements inLamp-Burners,of

V which the following is'a specification,

This invention relates to improvements in lamp burners, and one objectof the invention is to provide a burner in which will be obtained a moreperfect combustion than heretofore and in which the danger of explosionwill be reduced to a minimum.

A further object of the invention is to provide means toassure theproper trimming of the wick, and a still further object i to provide animproved means for holding the chimney in position.

V The several stated-objects, and such other objects as willincidentally appear hereinafter, are attained in such a mechanism as isillustratediin the accompanying drawings, and the invention consists incertain novel features which will be hereinafter first fully describedand then more particularly pointed out in the appended claims.

In the accompanying'drawings: Figure 1 is an elevation of the lampburner embodying my invention. Fig. 2 is a plan view of the same withthe wick cone removed. Fig. 3 is a vertical section on the line 3-3 of-Fig. 2. Fig. 4 is a detail section on the line H of Fig. 2. Fig. 5 is adetail perspective view of the trimming gage. Fig. 6 is a plan viewshowing a modification of the invention. Fig. 7 is a section on the line77 of Fig. 6. Fig. 8 is a plan view showing a further modification. Fig.9 is a section on the line 99 of Fig. 8. Fig. 10 is adetail perspectiveview of a portion of the chimney retaining ring.

In carrying out present invention, I may employ a burner base 1 havingthe usual perforated draft plate 2, to which a wick cone 3 is hinged, aswill be readily understood. Secured to the base 1, at intervals aroundthe same, are spring fingers 4 having eyes 5 near their upper ends,through which a chimney retaining ring 6 is passed, as will be readilyunderstood. The said ring 6 is usually constructed of spring wire havinga hook 7 at one end and provided at its opposite end with an eye 8 ringwill be held coupled aroundthe lamp chimney. Adjacent the eye 8 a springcoil 9is formed in the ring, which coil is expanded to permit theengagement of the eye 8 over the hook 7 and then automatically retractsso as to hold the said parts in engagement. To facilitate themanipulwtion of these elements, I provide a fingerpiece or handle 10 at the endof this coil 9 so that, after the chimney is in place over the burnerand upon the base 1, the ring may be readily fastened by pressing theend thereof against the chimney and then with the fingers of the samehand drawing upon the said handle 10, so as to pull the eye 8 over andinto engagement with the hook 7 as will be understood. The operation offastening the ring in position will thus be accomplished expeditiouslyand. easily, with Patented Sept. 16, 1913. Application filed December19,1912. Seria1No.737;732 I 1 jacent the upper end of the wick tube andshould be approximately of the same width as the wick tube so that airrising through the said tubes will feed the entire body of the flamerising fro-m the wick. The said draft tubes 12 being preferably disposedat an inclination or angle to the wick tube, as shown most clearly inFig. 3, any particles of soot or charred wick which might tend to dropupon the draft plate 2 will flow down through the said tubes 12 andconsequently pass out from the burner with out obstructing the drafttherethrough and causing imperfect combustion. The tubes are rigidlysecured in the base by being soldered or otherwise fixed to the draftplate and they may extend Vertically, as shown at 13 in Figs. 8 and 9,in which event they upper end-of the wick tube, as shown in Figs. 6 and7, which box would be open at f its lower end so as to'supply a strongcurrent of air to the flame.

i The'wick 16 rises through the "wick tube 11 and is raised or loweredto adjust the flame by the wick raiser 14 in the usual manner. Accordingto my present invention, however, the wick does not slide directly uponthe walls of the wick tube, but passes through a gage or trimmer tube 17which i walls of the opening in the draft plate through which the lifterpasses and thereby retain the lifter, and the tube attached thereitofi'n either its raised or lowered'p'osition. The tube 17 is provided111 its lower portion F with one or more longitudinal slots 21 whichaccommodate the star wheels of the wick raiser, so that neither elementwillinterfere wlth the operation of the other. The upper end-10f thewick tube is curved, as shown 1 clearly at 22, so as to form a gagewhen'the accompanying drawings, that I have pro- 1 i ingthe chimney willbe reduced to a mini- -j wiek is being trimmed to insure the propertrimming.

"'It will be readily seen from the foregoing description, taken inconnection with the vided means for supplying a constant and steadysupply of air to the top of the wick so that proper combustion will beassured an'dthe liability of explosions or of smokmum; The air or drafttubes provided by me; furthermore, serve to reinforce the base of theburner andv may be secured to the uppee-end of the wick tube so as toeife'ctually brace the same and thereby preventthe warping or twistingthereof, so that the appearance of the lamp is improved. also'essentlalto an economlcal consumption of oil and to obtain proper illuminationfrom the lamp, that the wick be carefully and the smoking of lampchimneys lsia'lso very commonly due to improper or hasty trimming of thewick.

Bymy improvements the trimming of the wick in a proper manner is madecertain,

even though the trimming shears be manipulated by a mere novice and forthis purpose I liave provided the tube 17. When it is desired to trimthe wick, the lifter 18 is. ma-

5 nipiilated to raise the gage or trimming tube IZ'thereby drawing thewick up above the 1 burner and exposing the upper curved endoffthetrimmer tube. The shears are then manipulated and caused to bearupon the upper end of the trimmer tube while being 1 manipulated, sothat as a result the wick Co lies of this patentmay beobtained It is} isgiven the proper curved trim necessary for proper combust on andeificlent illumination.
